我想要部署到Tomcat服务器8的WAR文件有问题。 使用默认值安装tomcat服务器（仅更改用户和密码）。 当我部署WAR文件时，我从Catalina.out日志中获取此输出：

我的猜测是MySQL连接存在问题，但我真的不知道应该在哪里指定连接字符串或类似的东西......数据库是在服务器上创建的， Grails中的DataSource指向该数据库。

我将上面的配置添加到Tomcat，但仍然无法连接。我开始对这个问题感到有点绝望。
答案 0 :(得分：0)
从stacktrace中提取;
Missing type or column for column[descripciono_descripciones] on domain[Ejercicios]
如果列名与camelCase用于下划线格式的约定不匹配，那么通常会从Hibernate获得MappingException。如果是这种情况，则必须使用mappings
column:部分中手动完成映射
例如，airportCode column: 'AIRPORT_CD'
修复也会解决部署问题（考虑到没有其他路障）。
答案 1 :(得分：0)
经过一周的努力解决这个问题后，我在一位同事和Tomcat doc的帮助下找到了解决方案。
配置是在context.xml文件中创建的，如下所示：
<Resource name="jdbc/turismoBackend" auth="Container" type="javax.sql.DataSource"
maxTotal="100" maxIdle="30" maxWaitMillis="10000"
username="youruser" password="yourpassword" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/yourdb"/>
值得注意的是，必须创建一个与root不同的用户才能让Tomcat访问MySQL，具有所有权限并授予选项权限。像这样：
CREATE USER '[yourUsername]'@'localhost' IDENTIFIED BY '[yourPassword]';
GRANT ALL PRIVILEGES TO [yourUsername]@[yourServer] IDENTIFIED BY [yourPassword] WITH GRANT OPTION;
那就是它！一切都在运行。
